Oakley Radar EV Heater Prizm Black Cycling Glasses

Unobtainium nose pads and ear socks

Oakley's exclusive Unobtainium material grips better the more you sweat, rather than becoming slippery. Thus, it keeps the glasses securely in place during high-intensity exercise; you will not have to constantly push them back up.

Why is this more important for sports glasses than for ordinary sunglasses?

Most materials used for nose pads become slippery as soon as they get damp, which is precisely when you need your glasses the most – during a sweaty workout. Unobtainium reverses that principle: The more you sweat, the more grip the material provides. This is particularly relevant for cycling glasses: They must not slip during a climb or sprint, when you really need your hands on the handlebars rather than your glasses.

O-Matter frame

This thermoplastic material, injection-moulded by Oakley, offers greater strength and flexibility than traditional acetate, and is designed not to shift or warp over time.

What does this mean for the durability of the glasses?

An acetate frame may warp slightly over time, particularly in hot conditions or with intensive use, causing the fit to lose precision. O-Matter has been specifically developed for sporting use, where the glasses are exposed to sweat, temperature fluctuations and physical impact. The material retains its shape and flexibility for longer, so that after a few seasons of frequent and/or intensive use, the glasses still fit just as well as they did on day one.

Prizm Black lens

This lens has a light transmission of 11% and is the darkest of the three lenses in this range, designed for use in bright light with a grey base colour.

When should I opt for the Black lens rather than the Sapphire one?

The main difference lies in how much light is transmitted and how colours appear. The Prizm Black lens (11% light transmission) is slightly darker than the Prizm Sapphire lens (12%), which makes it just that little bit more comfortable on the very brightest, sunniest days. With the grey base colour of the Black lens, colours are the most neutral and natural, which many users find more pleasant on the eyes than a lens with a pronounced colour tint. The choice between the Black and the Sapphire lens is primarily a matter of personal preference regarding how bright and colourful you want to see your surroundings, rather than a functional difference.

• Road cycling, running and other outdoor sports in bright, sunny conditions;
• Users looking for a universal, wide fit;
• Users who prefer a subtle, neutral colour rendering over a pronounced lens tint.

• Low-light or dark conditions – the Prizm Black lens is designed for bright light conditions, not for twilight or night-time use.

• 1 pair of Oakley Radar EV Heater glasses with a Prizm Black lens and a Polished Black frame
• 1 soft storage pouch

• A protective hard case – only a soft storage pouch is provided;
• A spare lens – Mantel does not sell spare lenses in other colours or clip-ons for prescription lenses separately for this model.

• Clean the lens with a microfibre cloth; never use a dry cloth or paper tissue, as they may cause scratches.
• When you are not wearing the glasses, keep them in the supplied storage pouch to prevent scratches on the lens. If you often carry the glasses in a bag or rucksack, we recommend storing them in a hard case.
• Avoid extreme heat, such as a car dashboard in the sun, to prevent the O-Matter frame from warping.
